'I've lived in Tenerife for 10 years - where Jay Slater went missing is treacherous and dangerous... it would be easy to get lost'

A car rental owner and blogger who moved to Tenerife from the UK 10 years ago says the 'treacherous' area where teenager Jay Slater went missing is a 'huge area' where it is 'easy to get lost'.

Andrew Knight, 29, selflessly offered up a number of his vehicles from his company Sanasty Car Hire to assist with the ongoing search, after 19-year-old Jay, from Lancashire, vanished on Monday (June 17).

Emergency workers, including the Civil Guard, mountain rescue team and fire crews, are still searching a 30-kilometre area, with the focus on three main ravines, in hopes to find the British teenager, who has not been heard from since he is said to have called his friend Lucy on Monday morning.

His phone is thought to have later 'pinged' in an open area around half a mile north of the Masca village, at around 8.50am.

Andrew, 29, who has lived on the Spanish island for a decade after first travelling overseas during a gap year, described the Masca and surrounding Rural de Teno reserve as 'treacherous and dangerous'. He told the Manchester Evening News that it would be 'easy to get lost' for inexperienced trekkers.

"The landscape in Masca is treacherous and dangerous; steep cliffs, loose rocks, cacti everywhere and large ravines," he said. "It is extremely difficult to find someone in the landscape.

"It's a huge area, most of it difficult to walk or climb. It would be easy to get lost. Lots of the mountains all look the same, the hiking trails all lead into each other and it's difficult to work out when one ends and another begins if you are inexperienced.

"The police are working tirelessly along with volunteers, Guardia Civil and mountain rescue teams. I chose to help because there is a mother missing her son; the family and friends are distraught.

"I knew i could bring some exposure and attention through my social media channels and when I saw people were struggling to reach the area, I decided to offer some of the rental cars I have for free to use as getting to Masca is not easy and is 50 minutes away from the main Tenerife South Tourist area."

Previously, Andrew described the air up in the mountains as 'very thin' with weather conditions that are 'constantly changing'.

"It does go very cold at night, especially with the thin air and the wind chill. It would be pretty cold if you were up there without jumpers and jackets and things," he said.

“I think the response has been very positive, and it will continue as well. It won’t just die away or stop, they will continue to share and keep going until there is some information or answers, or until he is found."

On Saturday (June 22), the sixth day of the efforts, officers reconvened at Rural de Teno Park on the north west of the island. It was another day with no major breakthroughs.
